Once roughly every two years and two months is the Mars opposition, when Mars and Earth line up in their revolutions around the sun. This is a rare opportunity to see Mars as it makes its closest approach to the Earth. It's time for some amateur space porn.

Today Mars reaches its opposition to the sun, although it won't quite be at its closest to the Earth until March 5th. Wired Science has advice on how to view Mars with your own telescope, but if you are sans equipment, you can make the Red Planet your very own camgirl by watching via the SLOOH SpaceCamera, starting at 8pm PT.
